MONTEVIDEO, Uruguay (AP) -- A prisoner in Uruguay has tapped into the U.S. ambassador's cellphone and sent messages to some of her contacts.

Officials said Tuesday that the inmate had access to Amb. Julissa Reynoso's voice messages.

Reynoso is in the U.S., joining President Jose Mujica on his official visit to Washington D.C. She told Uruguay's Canal 10 TV that the inmate used her voice mail password and sent messages to some of her contacts.
